Sony's Japan Studio is already at work on PS4 platformer Knack and is still helping Team Ico complete its much-delayed The Last Guardian.

The footage shows a totalitarian cyberpunk setting inhabited by humans and humanoid robots. The latter are able to see that each human has been branded with a number, and a woman is shown giving birth to a child with the number 1,000,000 - they're not all hers.

Skyscraper-sized rocket-firing dragons and a futuristic version of London also feature. Watch the trailer below and see if you can figure out what's going on.
